A B-pillar assembly 100 for a vehicle according to an embodiment of the present application is described below with reference to fig. 1 to 5, including: a B-pillar inner plate 1 and a B-pillar reinforcement plate 2.
Specifically, the upper end of the B-pillar inner plate 1 is fixed with a side wall upper side beam 200 of the vehicle, and the lower end of the B-pillar inner plate 1 is fixed with a threshold beam 300 of the vehicle; b post reinforcing plate 2 sets up in the outside of B post inner panel 1, and B post reinforcing plate 2 includes: the lower end of the B-pillar reinforcement lower section 21 is fixed with a sill beam 300 of a vehicle, the lower end of the B-pillar reinforcement upper section 22 is fixed with the upper end of the B-pillar reinforcement lower section 21, the upper end of the B-pillar reinforcement upper section 22 is fixed with a side wall upper edge beam 200, and the structural strength of the B-pillar reinforcement lower section 21 is different from that of the B-pillar reinforcement upper section 22.
Due to domestic environmental factors, the whole vehicle has light weight and can reduce energy consumption, the requirement of reducing the thickness of sheet metal materials to realize the light weight of the whole vehicle can be usually selected, and the structural performance of a vehicle body framework can be influenced. The B-pillar assembly 100 is the most basic safety structure of a vehicle against a side collision, and the B-pillar assembly 100 is the last line of defense hardware for protecting an occupant in the event of a side collision of the vehicle.
Since the compression space allowed in the passenger compartment in the event of a side collision is very limited, it is necessary to improve the structural strength of the B-pillar assembly 100 and reduce the amount of intrusion of the B-pillar assembly 100 into the passenger compartment. According to the method, the B-pillar assembly 100 is designed, the B-pillar reinforcing plates 2 are formed by sectional type design and splicing, and according to the observation of the deformation degree and position of the B-pillar in a side collision accident in reality or experiments, the middle section of the B-pillar assembly 100 is easy to deform, so that the chest position of a passenger can be damaged; in order to enhance the rigidity of the B-pillar assembly 100 and move the position of the B-pillar assembly 100 where the B-pillar assembly 100 invades and deforms to the lightest position of the human body, the upper section 22 of the B-pillar reinforcement plate and the lower section 21 of the B-pillar reinforcement plate are set to have different structural strengths, so that the rigidity performance requirement of the B-pillar assembly 100 can be met while the weight is reduced.
According to the B-pillar assembly 100, the B-pillar reinforcement plate 2 is divided into the B-pillar reinforcement plate upper section part 22 and the B-pillar reinforcement plate lower section part 21, the B-pillar reinforcement plate upper section part 22 and the B-pillar reinforcement plate lower section part 21 are designed to have different structural strengths according to the impact condition of the collision force on the B-pillar during the side collision of the vehicle, the effects of reducing the deformation amount of the B-pillar assembly 100 and strengthening the rigidity of the B-pillar assembly 100 are achieved, and the safety of passengers in the vehicle is protected.
According to one embodiment of the present application, the structural strength of the B-pillar stiffener lower section 21 is less than the structural strength of the B-pillar stiffener upper section 22. When the B-pillar assembly 100 is collided laterally, the structural strength of the lower section 21 of the B-pillar reinforcement plate is low, and the B-pillar reinforcement plate is easy to bend, so that the deformation of the middle section of the B-pillar assembly 100 can be reduced, and the injury degree to the chest of a human body is reduced; meanwhile, the structural strength of the upper section part 22 of the B-pillar reinforcement plate is high, so that the collision force can be transmitted to the non-collision side, and the degree of intrusion of the B-pillar into a passenger compartment is effectively reduced.
According to one embodiment of the present application, the lower B-pillar stiffener section 21 is made of HC340/590DP material and the upper B-pillar stiffener section 22 is made of CR1000/1500HS material.

Specifically, the B-pillar hinge reinforcing plate 3 includes: hinge reinforcing plate body 31, connecting plate 32 and burring 33. Wherein, an adhesive layer is arranged between the hinge reinforcing plate body 31 and the B-pillar reinforcing plate 2; one end of the connecting plate 32 is connected with the hinge reinforcing plate body 31, and the other end of the connecting plate 32 extends towards the B-pillar inner plate 1; the flange portion 33 is provided at the other end of the connecting plate 32 and is welded and fixed to the B-pillar inner panel 1. The flanging part 33 of the B-pillar hinge reinforcing plate 3 plays a supporting role, so that the rigidity of the B-pillar assembly 100 can be enhanced; during the assembly, earlier turn-ups portion 33 and B post inner panel 1 welded fastening, pass through the structure with B post reinforcing plate 2 and hinge reinforcing plate body 31 again and glue and be connected, structural change can not lead to taking place because of the welding heat to the structure glue like this, bonds insecurely.
According to one embodiment of the present application, the B-pillar inner panel 1 includes: b post inner panel lower segment portion 11 and B post inner panel upper segment portion 12, the lower extreme and the threshold roof beam 300 of B post inner panel lower segment portion 11 are fixed, and the lower extreme of B post inner panel upper segment portion 12 is fixed with the upper end of B post inner panel lower segment portion 11, and the upper end and the side of B post inner panel upper segment portion 12 enclose roof beam 200 fixedly.
According to an embodiment of the present application, the lower end of the B-pillar inner panel lower section 11 is fixed to the inner side surface of the rocker beam 300, and the lower end of the B-pillar reinforcement lower section 21 is fixed to the outer side surface of the rocker beam 300. As shown in FIG. 5, the B-pillar inner panel lower section 11 and the B-pillar reinforcement panel lower section 21 form a "U" shape, which is beneficial to transmitting part of the collision force of the B-pillar assembly 100 to the threshold beam 300, increasing the local rigidity of the lower end joint and reducing the deformation of the B-pillar assembly 100.
According to one embodiment of the present application, an energy-absorbing chamber 4 is formed between the B-pillar inner panel upper section 12 and the side gusset roof rail 200. The rigid part has stronger force transmission capacity, a larger impact force component force is transmitted to the upper end joint and is easy to break because an included angle is formed between the component force direction of the impact force at the upper end joint and the direction of the transmission force, and the energy absorption chamber 4 at the upper end joint is of a hollow structure, so that the absorption of the impact force component force at the upper end joint can be increased, and the deformation of the B-pillar assembly 100 is reduced.
According to one embodiment of the application, the B-pillar reinforcement upper section 22 is welded to the B-pillar inner panel upper section 12 and/or the side wall roof side rail 200. As shown in fig. 4, the B-pillar reinforcement plate upper section 22 is welded and fixed to the B-pillar inner panel upper section 12 and/or the side wall roof rail 200 to form the energy absorption chamber 4, which can effectively increase the local rigidity at the upper end joint.
